4. To make it perfect and to glamor the skin a little bit duplicate the layer that you've working on, and go to Filter> Blur> Smart Blur, set the Radius to about 12, Threshold about 30 or more, Quality: Low, Mode: Normal and now the skin is blurred, set the opacity of this layer to about 50% and use the Eraser Tool(E) to erase the blurred eyebrows, eyes, and lips and all except skin so the picture remain real

6. Now I saw the area bellow eyes- this should be also done with the Spot Healing Brush Tool. Very useful for adjusting the skin spots etc are Dodge Tool, Burn Tool and Sponge Tool- I won't explain how they work, because it's better for you to find it out by yourself!:)
